Final Exam
1) From your homework, what energy transfer and plasma chemistry processes do you think are important for the XeCl laser? Discuss.
2) Derive an expression for the collision-broadened linewidth in a gas laser, such as CO2.
3) Using an appropriate set of rate equations, describe a self-terminating laser. Give an example and estimate lifetimes, etc.
4) Design an optical system for a high gain laser such as a HF. Include a stable resonator, spatial filter and an amplifier.
5) Describe the electron energy distribution function in a continuous, 20-100 torr discharge driven CO2 laser, assume an appropriate N2, He, CO2 mixture.
6 a) Choose a diatomic electronic transition with high fluorescent yield. Sketch the potential surfaces.
6 b) Write a rate equation model describing the oxygen-pumped iodine system.
